“…Polyaniline is a conjugated polymer with appreciable electrical charge transport properties and consequently, it appeared as a functional polymer with tuneable electrical conductivity. [40][41][42] This has been possible due to the occurrence of benzenoid and quinonoid rings in the polymer chain at continuously varying proportions. Based on the different oxidation states of polyaniline, its electrical charge transport properties are modified, and also visible changes in the color of appearance are observed.…”

Polymer‐based materials are of high potential for application as active materials in contemporary electronic gadgets. The functionality of such materials is highly dependent on their oxidation state and requires fine control during their synthesis. Owing to that, we have designed a cost‐effective, simple, portable, system for calibration and the detection of the optical and electrical properties of polyaniline loaded on a paper substrate using a smartphone‐based colorimetric sensor. The vapor phase polymerization technique was adopted for preparing polyaniline. Colorimetric measurements of polyaniline‐loaded papers were achieved by estimating the hue, saturation and value (HSV) color parameter values using an open‐source smartphone application called “Color Grab (Color Detection)” during synthesis at different time intervals. The proposed sensor relies on the principle of Beer–Lambert law. The rear camera of the smartphone acts as a sensor and captures the light signal from the samples and provides information to the colorimetric app. The colorimetric results showed a promising correlation between the color parameter values with their electrical properties. The optical absorbance results of all polyaniline‐loaded papers are also in accordance with the H parameter values. The proposed sensor can be used as a portable smartphone‐based point‐of‐care testing kit to bring in‐situ control during synthesis.Highlights Conducting polymer on flexible cellulose substrate.

This study reports on a customized and revised approach to fabricate “nickel oxide decorated multi‐walled carbon nanotubes (MWCNTs) wrapped polypyrrole (PPy)” nanocomposite with enhanced room‐temperature thermoelectric (TE) properties. The nanocomposite is formed through three steps: MWCNTs functionalization via diazonium salt grafting of 5‐amino‐1,2,3‐benzene tricarboxylic acid; in situ generation on their surfaces of NiO nanoparticles with a homogenous distribution; the chemical polymerization of pyrrole using methyl orange as templating and dopant to wrap the MWCNTs‐(COOH)3‐NiO. Various techniques were used as characterization tools, including XRD, TEM, FTIR, Raman, TGA, XPS, and TE measurements. The PPy‐MWCNTs‐(COOH)3‐NiO nanocomposite exhibits significantly higher Seebeck coefficient, electrical conductivity, and power factor than PPy and PPy‐MWCNTs‐(COOH)3. The achieved enhancement in TE properties (figure of merit, ZTPPy‐MWCNTs‐(COOH)3‐NiO=1.51×10−2) is attributed to the presence of NiO, which acts as a dopant and improves the charge carrier density in the nanocomposite. These results offer the potential for waste heat recovery and large‐scale fabrication of high‐performance composites.
